We're dividing 22209991 by 458 
We want to figure out the number of times 22209991 can be divided by 458.

On to step 1:
2 divided by 458 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 458

Going ahead to step 2:
The number 458 fits into 22 0 times, leaving a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 458

Moving on to step 3:
The number 458 fits into 222 0 times, leaving a remainder of 222.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 222, we end up with 222.
Grab the next digit (0) from the dividend, add it to 222, then carry on: 2220 / 458

Moving on to step 4:
458 goes into 2220 4 times with a remainder of 388.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 1832 from 2220 leaves us with 388.
Take the next digit (9) from the dividend and append it to 388, then repeat: 3889 / 458

On to step 5:
458 can be fit into 3889 8 times, resulting in a remainder of 225.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we subtract 3664 from 3889, we get 225.
Include the next digit (9) from the dividend after 225, then repeat: 2259 / 458

Advancing to step 6:
458 can be fit into 2259 4 times, resulting in a remainder of 427.
Record the quotient 4 as the next digit in the result. 
Result so far: 484.0
Subtract 1832 from 2259 to get 427.
Fetch the next digit (9) from the dividend, attach it to 427 and continue: 4279 / 458

Going ahead to step 7:
When dividing 4279 by 458, we get 9 with a remainder of 157.
Put 9 as the next digit of the answer. 
Result so far: 4849.0
Subtract 4122 from 4279 to get 157.
Fetch the next digit (1) from the dividend, attach it to 157 and continue: 1571 / 458

Step 8:
458 can be fit into 1571 3 times, resulting in a remainder of 197.
The next digit of our result is 3. 
Result so far: 48493.0
If we take 1374 away from 1571, we end up with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 9:
When dividing 1970 by 458, we get 4 with a remainder of 138.
The number 4 becomes the next digit in our result. 
Result so far: 48493.4
The remainder is 138 after subtracting 1832 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 10:
458 can be fit into 1380 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 48493.43
If we take 1374 away from 1380, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
If we divide 60 by 458, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 48493.43
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
458 can be fit into 600 1 times, resulting in a remainder of 142.
The number 1 becomes the next digit in our result. 
Result so far: 48493.4301
The remainder is 142 after subtracting 458 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 13:
458 can be fit into 1420 3 times, resulting in a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 48493.43013
Subtract 1374 from 1420 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 14:
The number 458 fits into 460 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 48493.430131
Deduct 458 from 460 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 15:
20 divided by 458 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 48493.430131
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 16:
If we divide 200 by 458, we get 0 and a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 48493.430131
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 48493.430131, with a leftover of 2e-07.
